In this article, the authors review the role of bioethics in the processes of risk communication and socio-humanistic support for innovative development of technoscience, and analyze its commitment to the concepts of precaution and prevention. More focus is put on certain ethical challenges of the 21^st century associated with the development of artificial intelligence, deep learning in medicine, genome editing and ‘new parenthood’ practices. They have exploited the potential of bioethics in ethical and axiological reflection on the prospects of healthcare far-reaching reforms and in sociohumanistic assessment of transformed ideas about the human nature, family connections and established social order. It is shown that the experience of complex problem discussion and solving alongside with advisory mechanisms and bioethical procedures respond to pressing challenges of biotechnoscience and will be in demand in future.
